... . High performance military rockets can provide about 3300 feet per second of delta V. Space travel requires a very large delta V. The first objective of a launch to space is to ... into LEO from the Earth's surface requires about 30,000 feet per second of delta V. To escape the Earth's gravity field from LEO requires another 9,800 feet ... second. Landing on the Moon or other planets and returning home requires even more total delta V capability. ---- Answer provided by John W. Cole Image:K2S logosmall.jpg Question and Answer ...

... (SI), of the order of 2800 to 5000 s, but with an inherently low thrust and thrust density. However, this latter limitation is due to the restricted power available from present spacecraft. It is shown in this paper that a very much enhanced thrust density can be provided if a nuclear fission power source is utilised, with an electrical ... , use can be made of a 4-grid ion extraction and acceleration system, permitting present thrust densities in the range 0.1 to 0.9 mN/cm2 to ...

... methods of propulsion systems utilizes the ubiquitous infinite space, more specifically, vacuum. An extraction of thrust from the excited quantum vacuum is indispensable to the development of field propulsion. It is ... yields the coordination geometry of energy density. This paper describes the theoretical possibility of extracting thrust from the excited vacuum induced by controlling squeezed light, and identifies several supporting experimental concepts ...

... , non-dimensional numbers related to performance are beneficial, as they remove effects of scale. Traditionally thrust coefficients and C have been used to quantify the aerodynamic and chemical performance of a system respectively. However, it is argued here that in fact the thrust coefficient does not fully account for aerodynamic performance, as the impact of non-uniform flow ...
